AZIMUTHAL SQUARE ARRAY RESISTIVITY SOUNDING OF SHALLOW SUBSURFACE FRACTURE DISTRIBUTION IN PARTS OF THE EASTERN BASEMENT COMPLEX OF NIGERIA (Published)

Azimuthal square array resistivity sounding method was carried out at twelve (12) locations within Parts of the Eastern Basement Complex of Nigeria. The field data were collected using ABEM Terrameter with other accessories. For square – array, the location of measurement point is the centre point of the square and array size of 28m and 42m, 56m and 70m were used and each square was rotated in 150 increments about the centre point for a total of 3600.Data were analyzed using Origin pro. 8.0 Software. The results of the study showed the presence of fracture zones and seven (7) of the fracture zones were oriented in the NE – SW direction, while six (6) were oriented in the NW – SE direction indicating that the study area is has good potentials for ground water development.
